7 Claims. (01. 2 -213) My invention relates to an improved fastener member for attaching a. window guide strip or the like to a supporting structure and toinstallations of the same.

The object of my invention is to provide a simple and inexpensive means for attaching a flexible strip or the like to a supporting structure. My invention is particularly useful as a means for securing a flexible strip used in connection with an automobile window installation to the framework of the window channel. By reason of the fact that my improved fastener'member' may be used most advantageously for the purpose of attaching a window guide strip to a supporting structure, Iprefer to describe it in conthrough which a window pane 3 (Fig. 2) is moved Fig. 9 is a front, partly tipped view of the fasduring raising and lowering of the same. A flexible strip 4, a portion of which is shown in Figs. 1, 2, 4, 5, and 6, is attached to the support I and positioned so as to seal, in an effective manner, the passage between the lower surface 2 of the support and the window pane, (Fig. 2 as will be understood by those skilled in the art. Any suitable strip may be used, but in my preferred installation I have shown a strip having a beading 5 extending along onelateral edge thereof and adapted to be clamped against the surface 2 of the support by a portion of my fastener member (Figs. 2 and 6) for securing the strip to the support, as will be hereinafter described. A nap means 6 is provided on that side of the strip facing the pane 3, as most clearlyillustrated in Fig. 2. The strip 4 is attached to the support I by means of my improved fastener members which are provided with a resilient shank extending through a substantially circular aperture I of the support land having portions engaging an upper surface 2 of the material of the support adjacent the aperture.

Referring in detail to my preferred fastener member per se, I have shown in the figures a fastener made of one piece of sheet metal having a resilient shank comprising legs 8- and 9 of ribbon-like material connected at one end to form a nose I0. Two pairs of oppositely disposed notches ll|l and I2l2 are cut in the narrow edges of the leg 8 with the opposed notches I2--l2 adjacent the free end of the leg. As a result of this construction, shoulders l3 are provided on each narrow edge of the leg 8 intermediate the respective notches II- and I2 formed in that edge (Fig. 9). In my preferred form the portions l3--l3 extend laterally beyond the normal narrow edges of the leg 8 (Fig. .9) providing shoulders adapted to engage a surface of the support i. Material at the narrow edges of the leg 8-adjacent the end of the notches il-ll on the same side of the notches as the nose l provides shoulders I l-l4 (Fig. 9) for a purpose which will be described. Also, material at the narrow edges of the leg 8 adjacent the notches l2--l2 at those ends of the notches adjacent thefree end of the leg is flared outwardly, in my preferred form, providing shoulders ll5 (Figs. 3 and 9) adapted to engage an opposite surface of the support I from the shoulders l3-l3 when the fastener is in final assembly with the-sup-- port. At the free end of the leg 8, adjacent the v outermost end of the notches l2l2, I have provided a base portion l6 which is of greater width than the free end of the leg 8 so as to provide a bowed in a direction away from the leg 8 providing a shoulder I8 adapted to engage the same face of the support I as that engaged by the shoulder portions I3-I3 after the fastener has been finally secured to the support. A reduced portion i9 (Fig. 8) is preferably provided at the free end of the leg 9 so as to shorten the are taken by the width of the leg relative to the aperture 71 when the leg is in final attaching position with the support. A flange All, which is preferably of greater width than the leg 9, is provided adjacent the outermost end of the reduced portion I9 and extends in substantially perpendicular relation relative to the normal plane of the leg. The

* flange 20 is adapted to engage the same face of the support I as the shoulders I5-I5 of the base portion I6 when the fastener is in final assembly with the support.

- In assembling the parts of my installation, the nose III of the fastener is moved through the aperture 1 of the support I from a position outside the face 2 of the support until the fastener is in the first, or strip-receiving, position shown in Figs. 3 and 4. As a result of the fact that the distance between the arms 8 and 9 is greater than the diameter of the aperture 1, the arms will contract slightly while the fastener is being extended through the aperture so as to engage resiliently opposed walls of the aperture I. When the fastener is in the aforementioned first position, the outer corners of the material adjacent the narrow edges of the oppositely disposed notches II-II engage the wall surrounding the aperture I, and through reason of the fact that the notches III I shorten the arc of the width of the leg 8 relative to the aperture, the shoulder portions I3I3 engage material of the lower surface 2 of the support I adjacent the aperture 1 and the shoulders I4-I4 engage material of the upper surface 2 of the support adjacent the aperture, as most clearly shown in Fig. 3, whereby the shoulders l3l3 and l4-I4 cooperate to maintain the fastener member in said firstposition. At the same time the upper corner of the flange 20 at its outermost free edge engages the lower surface of the support I, as most clearly shown in Fig. 4. The strip 4 is now moved into position with the fastener-member so that the bead 5 is engaged by the clamping portion I1 at the free end of the base I6, as most clearly shown in Fig. 4. v

In moving the fastener into final position for securing the strip to the support, pressure is exerted on the arm 8 by a suitable tool to move the arm 8 outwardly away from the material -of the support adjacent the aperture 1 and inwardly until the shoulder portions I6-I6,engage the lower surface 2 of the support, at which time the bead 5 will be clamped adjacent the lower surface 2 of the support so as to secure firmly the strip to the same. When the fastener is in the aforementioned final position, the shoulders Iii-I3 of the leg 8 and the shoulder I8 of the leg 9 engage the upper surface 2 of the support I adjacent the aperture I so as to prevent unintentional withdrawal of the fastener from the support in the direction of the window pane. It

-bers maybe used to attach the strip to the support, but it is necessary that a corresponding numberof apertures be located in correct position in the support to receive the resilient shanks of the fasteners.

Thus by my invention I have provided a novel fastener member of inexpensive construction which may be easily assembled with a support and which is provided with efiicient means for clamping a strip to .a face of the support whereby it may be maintained in secure assembly therewith.
